Can you get the lid up high enough to get something thin in there like a stir stick for paint. If so try to use the stir stick to get it unjammed. Use a hammer and a screw driver to try to chisel the hinge off.

If you have a drill take bit that is a little bit bigger than them two spot welds and drill them out. Then use a hammer and a screw driver and tap and the back lip of the lid and the back will pop right up. For the repair a couple 1/4 20 bolt and nuts, rivets, or have them welded back together.

Someone should send this thread to Tuffy. Quite a testament to their products! I've got the Tuffy center console, overhead console, and glove box. I've got several spare keys so hopefully I never run into this situation! :-)
